Reading some of the reviews about F, it is clear that there are a few misguided and unimaginative people out there. Fair dos to them - they are entitled to their own opinions! For the more open-minded people out there:
This film marries together several different film genres to create quite a unique experience. It relies on the audience being able to envisage in their own mind how the story progresses and ends, giving just enough clues to help them along the way.
If cut and dry endings and 100% gore is what you are after, then this isn't going to be the film for you. While F does have several toe curling scenes, that is not all it's about.
I challenge all avid film buffs and viewers to watch this film and identify all the 'non-horror' influences and techniques that have gone into its making. Appreciation for these qualities will mean appreciation for a very talented film maker - hopefully with plenty more films to come!
